MEDICINE .ADMINISTERING DEVICE.

i Application yfiled November 27, 1926. Serial No. 151,186.

Thisl invention relates to a medical appliance, the general obj ectl ofthe inventionbeing to provide means for applying powder to a cavity ofthe body, such as the throat.

Another object oi' the invention is to provide a cylinder and a piston,the piston having an annular groovefadjacent one end thereof which formsa powder receiving chamber` with a removable hopper litt-ing over theend oi' the cylinder and adapted to receive a quantityofpowder which isdrawn into the cham.- ber when the piston is retracted, after which thehopper isremoved and t-hen by projecting the cylinder, after the deviceis placed in the cavity to be treated, the powder is ejected againstthewalls of t-he cavity.

Another object of the invention is to provide an annular groove at theother end of the cylinder which is of less dimensions than the iirstgroove so that by reversing the piston, a powder receiving chamber orlless dimensions will be provided `t'or administering a small quantityoi' powder. v

This invention also consists in certain other features of constructionand in the combina.

tion and arrangement oi" the several parts, to be hereinafter fullydescribed, illustrated in the accompanying drawings and specilicallypointed out in the appended claims.

- 'erence will be had 'to the accompanying drawings wherein likecharacters denote like or corresponding parts throughout the severalviews, and in which zv Figure 1 is an elevation of the invention withthe hopper thereon. y

Figure 2 is a longitudinal sectional view through Figure 1. j

Figure 3 is an elevation with parts in section, showing the hopperremoved and the chamber iilled with powder.

Figure 4 is a top plan view of Figure 1-. In these drawings, the numeral1 indicates a tube or cylinder, preferably formed of hard rubber, andone end of which is tapered and threaded and divided into a number ofjaws 2 by means of the slots 3. A screw cap et tits over the threadedpartv and acts to contract the jaws when screwed inwardly. Within thetube 1 is slidably arranged a piston 5. This piston is formed with thereduced portions 6 and 6L1 adjacent its ends, an enlarged portion 7,preferably of prolate form, is connected with the reducedpart 6, while asimilar porl tion 7 is detachably connected with the part 6a so that thepiston can be assembled in the In describing my invention in detail,ref-y cylinder. This portion 7 a acts as a handle for moving thepistonin the cylinder. The upper end of the cylinder is tapered toreceive a part of the portion 7 as shown in Figure 3, when thejpiston isin yretracted position, and by providing the cap t and threaded jaws 2,the lo-wer end of the cylinder can be made to lit snugly a part of thepiston and by tightening the nut on the jaws, the piston can be lockedagainst movement in the cylinder. A removable hopper 9 iits the upperend of the tube or cylinder. l

When the device is to be used, the powder to be administered is placedin the hopper after the piston has been projected, as shown in Figure 2.Then the piston is retracted to the position shown in Figure 3, and asthe piston is moving inwardly, the powder in the hopper, will be drawninto the chamber formed by the reduced part 6 and the walls of thecylinder. After the piston has been fully retracted, the hopper isremoved `and the nut 4L turnedto lock the parts in the position theyoccupy in Figure 3. The device is then placed in the mouth or othercavity to receive the powder and then the nut is. loosened and thepiston projected by means of the handle 7a which will eject the powderagainst the walls of the cavity. It' desired, the part 7 can be used toplace some of the powder on certa-in parts of the walls of the cavity.

The smaller applicator-7a may be used by attaching and reversing thepiston and reattachng its smaller diameter varies Vthe quantity ofpowder and the distribution thereof. i i

Thus it will be seen that I have provided simple and effective means forejecting powder and the like into the throat or other cavities. Y

What I claim is 1. A medical appliance of the class described,comprisingv a tube, a piston slidably arranged therein and having areduced part adjacent one end which forms a chamber with the wallsot'the tube when the piston is in retracted position, and a hopperdetachably connected with the tube for enabling material to be drawninto said chamber when the piston is retracted after being projected.

2. A medical appliance of the class V described, comprising a tube, apiston slidably arranged therein and having a reduced part adjacent eachend forming a chamber with the walls of the tube when the piston is inretracted position, a hopper detachably condry powder to the cavity ofthe body,' com-y nectedv with tl'nefl tube for emabting material to bedrawn into said chamber when thepston is retracted after beingprojected, the extreme end of the pistonhaying'a rounded en;- largementthereon for bringing the powder into actual contact with the` minous;mem,- brane of the cavity, the ends of the piston being of differentdimensions.

3. A medical appliance comprising a tube, a piston slilda-bly arrangedtherein and` `hav` ing its ends reduced, an enlargement at eachextremity othe pistonand forming with the reducedv parts and the Wal-lsof the tube anmilrlar spaces 0r chambers when the enlargement is inengagement Wi-tlrtheend of the tubefa detachable hopper for engaging oneend of the tube and one of said enlargements being removable to `permitthe piston to be placed in the tube.

4. `A medical` appliance fon administering prising a. tube having avpiston slidably mounted' thereiinfsaid piston hayingv a reduced portionad'acent oneend, which forms With the walls o the tube an annular chamfkberwhen the piston isfretraeted, the opposite A v end of the tube beingsplit and a threaded zap on the split end for enabling this end to bepressed against the piston.

5r -Amedical appliance for administering dry powder to the cavity of thebody,` comprlsing a tube having a. `piston slidably mounted therein,said' "piston `having, a re-` duced portion adjacent one end, whichforms with the Walls of the tube an annular chamber small end thereof. tY
